4.2 lever change

I looked at doing it in the car but felt it would be a nightmare and ***** to do on my 727.

I’m a little confused as to your original post, are you referring to drag racing or road racing? I’m guessing you want the car to hold more rpm between shifts? And are referring to the 1/8th or 1/4 mile?

I ask because if you have a stock 904 you may want to try the 3.8 lever first as an upgrade. The stock ones I thing are like 2.7 or lower even.

If you really want to go nuts I do have a 5.0 lever I’d sell.
